Table of tribes, based on the chrysalis. 



Wing cases decidedly protuberant below the general course of the under surface of the body; 

 1 tonf,'ue and antennae not nearly reaching the uncovered part of the abdomen : carinae of 

 boily rarely raised to abrupt angles or points. 

 Anterior and posterior halves of body heteroniorplious, sometimes the one, sometimes the 



other the slenderer, the head usually well distinguished from the frontal prominence 



Rhodoceridi. 

 Anterior and posterior halves of body honiomorphous, the former the slenderer, the bead 



scarcely distinguishable from the frontal prominence Anthocharidi. 



Wing cases not protuberant below the ventral line; tongue and antennae reacbing the un- 

 covered part of the aljdomen; cariuae of body generally raised to sharp projections, espe- 

 cially about the middle of the thorax, and the basal half of the abdomen Pierldi. 



Table of tribes, based on the immjo. 



Antennae gradually increasing in size, the club ill-defined, slender, cylindrical and apically 



subtruncate; palpi stout, the apical joint short; prevailing colors yellow Rhodoceridi. 



Antennae with a distinct, broad, subspatulate, depressed club; palpi slender, the apical about a-s 

 long as the middle joint; prevailing colors white. 

 Third subcostal ncrvure of fore wing forked near the middle; precostal uervure of hind 

 wing straight; middle tibiaeshorterthan femora; eighth abdominal segment posteriorly 



prolonged above in the male Anthocharidi. 



Third subcostal uervure of fore wings forked at extreme tip only; precostal nervure of 

 hind wings strongly bent outward; middle tibiae at least as long as femora; poste- 

 rior margin of eighth abdominal segment entire or notched above in the male 



Plerldl.

Imago. Prevailing colors yellow and orange, marked with black. Head : Front but 

 little and always irregularly tumid ; antennae moderately stout, equal to or shorter 

 than the abdomen in length, the club ill-defined, increasing in size very gradually, 

 cylindrical or depressed, long and rather slender; palpi very short, less than half as 

 long again as the eye, moderately stout, with a very thin and short fringe of hairs, if 

 any ; apical joint minute, the basal extraordinarily large, at least as long as the middle 

 joint and sometimes more than twice as long. Patagia long ,aud slender, the posterior 

 lobe considerably elongated ; the third branch of the subcostal nervure of fore wings 

 with a long fork; precostal nervure of the hind wings very short or altogether 

 wanting ; middle tibiae of the male shorter than the femora. Eighth abdominal seg- 

 ment of male prolonged above, usually as a distinct hook, but sometimes as a lami- 

 nate expansion ; hook of upper organ of appendages small ; posterior edge of clasps 

 produced once or twice to a point, usually incurved. 



Egg. Tall and very slender, pretty regularly fusiform, only larger below than above, 

 the summit delicately rounded, the vertical ribs pretty numerous, not high, but deli- 

 cate and distinct. 



Caterpillar at birth. .\ppcndages of body rather or very short and expanding 

 greatly at tip into a wine-glass or club shaped bulb almost or quite as broad as long; 

 the uppermost series laterodorsal, longer at the extremities of the body than on the 

 middle segments.
